The Fluke Calibration 1620A DewK Thermo-Hygrometer revolutionizes environmental monitoring for calibration laboratories.
Two types of sensors are available from Fluke Calibration, and the DewK may be originally purchased with either one. The
high-accuracy sensor ("H" model) reads temperature to ± 0.125 °C over a calibrated range of 16 °C to 24 °C. Relative humidity
readings are to ± 1.5 %RH from 20 %RH to 70 %RH.

All DewK sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data
and NIST traceability. Fluke provides exceptional uncertainties, including total test uncertainty ratios better than 3:1 for both
temperature and relative humidity—even for the high-accuracy sensors!
